Abstract

The invention discloses a hydrogen-aluminum metal compound which comprises 20 parts by weight of two groups of aluminum powder, 1-3 parts by weight of hydrochloric acid serving as a triggering agent, 3-6 parts by weight of pure water, 6-12 parts by weight of carbon powder, 10-15 parts by weight of an organic solvent and 3-5 parts by weight of solid sodium hydroxide. The preparation method comprises the following steps: generating aluminum chloride and hydrogen in a first reaction zone, generating sodium metaaluminate in a second reaction zone, and generating aluminum chloride and hydrogen under the action of sodium metaaluminate and hydrochloric acid, and allowing the aluminum chloride in the second reaction zone to enter the first reaction zone, the aluminum chloride in the first reaction zone to be simultaneously dissolved in ethanol to generate a hydrogen-aluminum compound with high stability and to generate a large amount of heat, and releasing a large amount of hydrogen while the heat is absorbed by utilizing a water gas principle of carbon powder in the first reaction zone; and the preparation method is efficient and safe.

Description

technical field [0001] The invention relates to the field of composites for hydrogen. A large amount of hydrogen can be produced simultaneously by preparing a hydrogen-aluminum metal composite, and the invention belongs to the application field of real-time hydrogen production. Background technique [0002] Hydrogen, the chemical formula is H 2 , under normal temperature and pressure, is a highly flammable gas. Colorless, transparent, odorless, tasteless and insoluble gas. Hydrogen is the least dense gas known in the world. The density of hydrogen is only 1 / 14 of that of air, that is, at 1 standard atmospheric pressure and 0°C, the density of hydrogen is 0.089g / L. Therefore, hydrogen can be used as filling gas for airships and hydrogen balloons. Hydrogen is the substance with the smallest relative molecular mass and has strong reducibility. It is often used as a reducing agent to participate in chemical reactions. [0003] In industry, hydrogen is generally produced from...
